"Fig; 4'is a',

roller, as there shown. Fig. 6 is a vertical sectional view, on line 66of Fig. 5, showing the manner in which the usual metal bar,

as seen in Fig. 5, may be connected with the sash holding means attachedto the sash."

Fig. 7 shows in side elevation a portion of a sash with a modified formof sash holding means applied thereto. Fig. 8 shows in front elevationportionsof a sash having another modified form of holding means mountedthereon. Fig. 9 shows in side elevation that which is seen in Fig. 8with the window frame in section.

In Figs. 1 to' 3, inclusive, A representsthe window frame, B, the sashmovable in the guideway a, formed in the frame A, and B. isrgo asupplemental sash fixedly secured in the frame above the sash B.ltneprcsents a spring roller which may be of the usual construction', socommonly used at the present time for supporting and more or lesscounterbalancing sashes, (as for instance in railway cars,) such rollerbeing mounted in any desired manner in or on the window frame A to r sosupport or balance sash B. Attached to this roller R, at its oppositeends, as shown, is a chain, cord or other flexible material 1', whichpasses from one end of such roller, as seen at the right of Fig. 1,downwardly and around a stud .c, of suitable" construction .mounted onone end of the pivoted lover C of sash holding means D, which in turn issecured to the sash A near its upper right hand corner,thence along andnear the top portion of such sash to and around a similar stud cmounted'on pivoted lever C of sash holding means D, attached to sash Anear its upper lefthand corner, thence upwardl to roller R1 to whichitis securednear its left hand end.

This chain 1' is free to-slide or move onstuds c and c, or on either ofsuch studs, so that the weight of the sash is about equally distributedonthis chain, cord or other flexible material,

both sideportionjsof'the window rame. As a result the levers C and C aremade tobear upon .the opposite-sides of the window frame withsubstantially an equal pressure to'hold the-sash in theframe'againstrattling and to theends of these levers, which bear againstthe frame, are beveled and bear against bev eled surfaces formed" uponthe opposite sides" prevent the freefassage of air anddirt past the sideedges'o the-sash. As here shown the frame A the chain or other flexiblematerial winds or unwinds therefrom and the sash B may becorrespondingly raised or lowered the same if such chain or flexiblematerial were secured directly to the sash as seen in prior patent No.681,688 dated Sept. 3, 1901. As here shown this chain or flexiblematerial is indirectly connected with the sash by being I passed overthe studs 0 and 0 attached to levers (J and (1, respectively, so thatthe weight of the sash is exerted on said chain or material to move suchlevers on their pivots and consequently move the opposite ends of suchlevers into close and intimatecontact with beveled surfaces 7) and. b ofthe guideway (1- formed in the frame A. The guideway'a is clearly seenin cross section in Fig. 3 ,where the lever C is shown in engagementwith the beveled surface 6, there. bein similar surface on the oppositeside of the frame A for the end of lever C to bear against, which isdesignated as 7).

Whenever the sash B is lifted, so as to release the material r and theroller R of its weight, such roller winds up, if unrestrained, and, ifthe sash under-balanced by such roller, the levers, as C and O, are notforced against the beveled surfaces 1) and b to such an extent as whenthe sash is fully balanced and such sash is not held in its frame astightly and coi'isequently may be lifted with a less expenditure offorce by reason ofthe lesser stress of the spring in the roller and ofthe consequent lessened holding acting of these lovers, (of these sashholding means, as D and D,) on the window frame. The angle that theselovers 0 and C are arranged at relatively to the window frame is suchthat the levers tend to move away from the frame as the window islifted, to open such window, and yet is also such thatthe ends of theselevers may remain in contactwith the window frame as the sash; is movedin the closing direction without unduly engaging therewith v andmaterially affecting such closing movement. Thus the sash may be movedin both directions with these lovers, as C and C in continuousfrictional contact with such win dow frame, with the spring roller, asR, ex erting its full force upon. such levers in partially supportingsuch sash This is also the case both normally and while opening and"closing the window. From this, it will be seen that these sash holdin gmeans are more or less in continuous frictional contact with additionalsash r dding are secured to the 1ower As here sho means, as D f portionof the sash B, as seen in Figs. 1 and 4.

As here shown each of these sash holding means, as D and D is providedwith a slid bolt, as d and (1, respectively, which is provided with abeveled engaging end to engage with the beveled surfaces, as d and d,(see Fig. 4,) respectively. Each bolt is sprin pressed into contact withits corresponr ingly beveled. surface of the guideway in a Wellknomimanner and such bolts are moved. against the stress of their springs bylevers, as d and (1 respectively, as will be readily understood from thedrawings herein.

Each of the sashholding means, D, D, D ets, act independently of eachother in holding the sash in its guideway and to substantially the sameextent at opposite sides of the sash, because the force exerted by thespring roller and the springs acting on the sliding bolts tend toeqlpalize and force the sash edgewise until su stantially an equalresult is reached at each of both edges thereof.

To 0 en and close the window the levers, control ing the sliding bolts,as d and d, of

holdin means as D and D are mani ulated in a well known manner and thesee i is relieved, in Whole or in part, from their holding action. Withthe sash thus relieved and the application of still more force in thesame direction to such levers the sash is moved in the openingdirection, then without releasing the levers and applying force to thethumb pieces in the opposite direction the sash is moved in the closingdirection. U on the release of these slidin bolts, as d 21TH d, thefrictional contact 0 such bolts and the levers, as-C and C, may be suchas to hold the sash in the desiredposition, even when some considerableforce is a plied thereto. When the sash is about he anced by the springin the roller R the holdin 3.6'01011- of the levers, as C and C, of theholding-means D and D ma be suflifcient to hold the sash in any desirecposition in the guideway and prevent its moving therein without forcebeing applied thereto to overcome the fri tional contact of the holdingmeans D and on the opposite sides of the frame.

If the'sash be underbalanced the slidi g bolts, as d and d of holdingmeans D? and may be made to engage with recesses Sta-t;- ably'formed inthe beveled surfaces as in practice is quite commonl done at the s outday and thus be held in the open 'posi? tion, and ifover balanced thesebolts niay engage with suitable recesses or ab'c tmen .s to

hold the sash inthe'closed ositioiiu also as is v inclusive, they maybe. arranged-ac seen in Figs. 5 1307, inclusive, Where they takejontheform of rock sh as there seen. As seen in Figs. 5 and 5 t1 ckshafts,j(one ;only being. shown the ing substantigllly g duplicate. butleit hand instead of right,) as is provided with two arms, as c and 0one of which, as c, is provided with an oblong opening or recess toreceive, as there shown, one end of the flat bar of metal in an endwisedirection, which bar is quite commonly used in'connection with a band offlexible material for connecting spring rollers with sashes. This bar 1passes through a hem or ocket in the lower portion of the web ofiiexible .material, as r, and one end is received by the oblong openingor recess of the sash holding means at one side of the window and theother end of such bar passes through a similar opening or recess 111 onearm of the rock shaft at the other side or edge of the window, as willbe readily, understood by those skilled in the art of windows.

The force of the spring of roller R is exerted on the arms, as 0 ofthese rock shafts, through the web 1" and the metal bar r", and tends torock such shafts in their bearings, as I, which are secured to the sashB as shown. This sash B is adapted to move up and down in the guidewayformed in the frame A. The other arms of each of these rock shafts, as 0rests or frictionally bears against the inner side portion of theguideway on opposite sides of the window so as to force the sash againstthe opposite or outer side portion thereof, as is clearly seen in Fig.6.. These arms, ass and c are arranged,.as

. here shown, at nearly right angles to each ,other andconsequentlyforce exerted in an 3, then such portions,

construction at the upward direction on, arm, as 0 tends to force arm,as laterally, which in turn tends to force the sash laterally, in theopposite direction. If desired these arms, as 0", may be provided, asseen in Fig. 6 with stop or buffer portions, asx, designed to contactwith portions of the window frame, as m, on the opening of the window toits full extent construction of rock shaft and buffer'extension,as ac,to the arm, as c", is used in the con struction of window frame seen inFigs. 1 to as w, of these arms, as 0', would contact .with that portionof the window frame just below the spring roller, seen in Fig. 2, whichis a common form of car resent time. of arranging these roe shafts asseen in Figs. 5 and 6 they may be arranged as seen in Fig. 7, or as seenin Figs. 8 and 9 of the drawings. In ei her case the mode of operationof t 1e rocl: shafts is the same, so far as concerns the holding of thesash in the frame and the action of "the buffer portions of such rockshafts, aswill be manifest to a mechanic.

' In each construction of parts seen in these Figs. 5'to 9, inclusive,the rock shafts are arranged with their, arms within the space formingthe guideway in which the sash moves in opening and closing the windowand those portions of the sash to which the rock shafts are attached aremoved laterally in any If this Instead I or at substantally right anglesto the direction in which the sash moves in opening and closing thewindow.

In Fig. 7 the arms, as c and c of the rock shaft C are arranged to movethe sash in the opposite direction to that in which the sash is moved inFigs. 5 and 6. The arm 0 of this rock shaft 0'', in Fig. 7, is provided.with a stud 0 around whicha chain, cord or other flexible material maypass, in the manner indicated in Fig. 8, the action of which on the rockshaft is the same as is that of the web or other flexible material onthe rock shafts in the construction illustrated in Figs. 5 and 6. Theupper portions of surfaces a:

of these arms 0 of the rock shaft (3 serves the same purpose in the sameway in the form and arrangement seen in Fig. 7 as is served in the formand arrangement of rock shaft arms seen in Figs. 5 and 6.

A somewhat different form and arrangement of rock shaft arms is shown inFigs. 8 and 9 than is seen in Figs. 5 to 7, inclusive. In Figs. 8 and 9therock shaft arms, as c and c, of rock shafts C are arranged to forcethe sash toward the exterior portion of the guideway in which the sashmoves and a separate arm, as :0 carries the buffer surface which is toabut against a portion of the frame in which the sash moves to protectthe sash supporting means, (when in the form of a spring roller mounteddirectly over the u per portion of the sash) from injury arising rom thesash striking such means in the opening of the window. The operation ofthese buffer portions of the rock shafts is the same one of the formsand arrangement of arms of the rock shafts that are herein shown. Theserock shafts are'preferably mounted on the top edge of the sash B andthey are arranged at opposite edge portions thereof to bear againstopposite side portions of the window frame A", as shown. The arms, asc", of these rock shafts (1 are each provided with studs, as 0", whichstuds are provided with headed portions to hold .the chain, 'cord orother flexible material attached to a spring roller or other balancingor sash supporting device or devices from slip ing off the ends of suchstuds, the body holdin such chain, cord in the other direction. Figs. 1and 2, having of t e arms, as 0, etc? from slipping off A chain, as seenin its opposite ends secured near to the opposite ends of a s ringroller, as there seen or otherwise, may \e employed in the constructionseen in Figs. 8 and 9 if desired. As

shown in Fig. 8 the chain, cord or other flexible material, as 1',passesfrom sash sup porting device or devices down and-around one stud,as 'c", thence along, towardand around the other stud, as c, and thenceto the sash supporting device ordevices again.

When studs like those herein shown are employed, in connection with thelever portions of sash holding means, as the means for connecting thesash supporting means with studs form a convenient form of connectingmeans between the sup orting and holding means and their use as iereinset forth will naturally suggest the use of other means by which thesame work may be done in substantially the same way to accomplishessentially the same result. As here shown, the flexible material of thesash supporting means is readi v moved relatively to the sash holdingmeans by applying a sufhcient force thereto to overcome the forceexerted by the supporting means and when this is done such material canbe readily slipped or hooked over such stud or studs and also readilyslipped off or unhooked therefrom.

In the several forms of sash holding means herein shown, wherein leversare employed, it is preferable that the angles, at which the arms ofsuch levers are arranged, (which bring pressure to hear to hold the sashin its frame) relatively to the side portions of the frame, be such thatabout the same force be exerted by such levers on the frame in bothdirections of movement of the sash, in opening and closing the window.The several forms herein shown having their lever portions connected tothe. sash supporting means are convenient forms and are well adapted todo the work they are designed to accomplish and these forms willnaturally suggest other forms which will have substantially the samecoactiv relations with the other parts employed in making up the com:binations of members or elements hereinafter particularl pointed-out.

In each embo iment of this invention herein shown and described the modeof operation is such that ,Ih'e sash holding means, having these leverportions connected with the sash supporting means, are continuouslyacting to more or less hold the, sash in the guideway, whether thewindow be closed or is being opened or closed. This revents the sashfrom suddenly and quickly alling, when the window is open, and lessensthe dangers arising from such accidental falling of window sashes.

Other forms of sash holding means, as I) and D or other desirable forms,may be employed to" aid the sash holding means,

having the lever portions, to firmly nold the sash in its frame withgreat advantage, whether it be when the window is closed or is open.When such other forms are thus employed it is preferable that each suchmean;- should be prov ded with manually operable parts which are 0erated when the window is to be opened or c osed to partially releasethe sash in its guideway.
